Is it possible to put in an option to rate the scanlation quality of a group for each manga series? Something like the rating system for group quality in anidb so it's easy to tell what quality the scans are without actually downloading them.

I've considered doing this in the past--but from talking with other people, it seems most likely that it would be abused. We don't want to be responsible for discouraging groups after they put a lot of hard work into one of their releases. I think it's more important that we focus on the series & the authors and their quality, rather then the individual groups. I thank you for the suggestion, but I do not have any plans for implementing something like this at this time.
